To all whom it may comm; 7

e it known that 1, am: ,PiiRNA, a United States, f residing at citizen of the Phi-ladelphia in the county ofPhiladelphiaand State of Penn'sylvania, haveinvented new and useful Improvements'in Excavacarrying a guide ,for a pneumatic hammer or driver which is; adapted to follow the shoring as thesame is. to be driven into place, theraising and lowering of the hammer and the movements of the trucks being controlled by a suitable source of power provide such asengin e, 7 ,1

' if further object of the invention is to. an adjustable frame for an excava= tor. whichmay be adjusted before-being set up to accommodate the width of the-trench and the height of which' inay bey'regulated according to theheight of over head structures in the localitywhere the work is be-= ing done. v a

A still further object of the invention is to provide, an improved trolley having improved means for holding the bucket hanger with the bucket in a raised position.

Another object of the invention is to:pro-' support adapted to be .pi v.

vide a locking oted to the. trolley of an excavatorwhich will .be actuated by the shaft in a bucket hanger to locking support, the latter then being returned to with the I bucket hanger "with the be supported to, relieve-the hoisting rapes or tablesandat thesaih time revent the r pair of uprights are suitably bt'lcke'tfr'om descendingnn'til desired.

7 With these 'endsin view invention consis s in the details of construction and combination ar elements hereinafter setfor'th a a than specifitauy designated by-Ithe claiin.

Fig. 5, is a longitudinal vertical sectioufl thereof, a portion ofthe track being broken away to clearly illustrate the construction.

In carrving out my inventionasher'e embodied 2 represents a trench which'isbeing j excavated for th'e'laying of a se'wer,ip'ipes or I v other undergroundobjects, theside walls of l the-"trench being held injj ositionfo'r ressed f by suitables'horing' boards 3. f' r H Along the course of .the trench to bewexcavated are manner the runners lor'joistsfi whichcarry, the rails 6 of the track for the excavating frame.

The conveyor frame consists of a number of uprights7, arranged in pairs preferably converging toward their upper ends, each of the uprights of a coacting pair have crossed bars 8 and 9 secured thereto, the former bein'g near-the lower ends andlthe latter near the upp'e'r'endsof the uprights. These cross bars havin a numbero'f. holes '10 whereby the cr ss bars 10f one upright may be i s i r of the enacting uptened to the cross bars or their 'eq walent right by means offbolts 1 v V Thelower ends of each of therunjners 5 may tracks placed directly s5 v placed a number pf ties or sleep- 7 ersfl to which are fastened in any suitable the ZcOacting mounted on cross bars 9 and to these projections are adjustably secured the extension members legheld in their desired adjustments by bolts 16 inner ends of rcoacting or their equivalentpassing through the pro jeetions of the uprights and throughholes 17 in the extension"membersf= sion members carry reach members 18 the pairs overlapping and held in position or their desired. adjust ment by bolts 19' ortheir: equivalent passin g through holes 20 injtheoverlapping ends.

The locking suppoi't,1nay be manually actuated by a pull p0. 61' iastened'to its outer end or another'pull' rope 'ti2 attaehed to some suitable portion'fof its inner v end and running over a sh'eave'fili between.

After the bucket has been transported the point desired, the bucket is again hoisted the necessary distance which will permit the inner ends of the members 56 to pass the shaft or axle 53 at which "time said locking support may be moved from the path" of travel .of the shaft or axle *53 in itsdownshown in Fig. 1 and moved tothe proper ward course by pulling upon any one of, the pull'ropes '61, 62, or.68 and as two ofv some, distance from the trolley itself, the bucket may be these pull ropes are located:

v During the excavation of thetrench along one portion of the operation,

or piles may be driven by mechanical means supported by the same framework which carries the bucket trolley. To" do this work the shoring boards position by running this supporting truc-k'23along the track 21 and then releasing its hoisting rope or cable so that the hammer rests upon the end of the shoring-board to be driven into the ground. after which the operatingfluid is turned on and the pile driver permitted to follow up the shoring board as it gradually enters the ground after the shoring board has been driven home the pile dri moved to the position of ver is raised and "of placing the shoring boards limits of sa d members, the ends of said rods ing beyond the side'platesj and adapted to shoring boardsare set in position as. the pile driver 29 then the next shoring board to be placed in position.

work very VVhere' its necessary to do the the trench quickly and where the digging of can be expedited to keep up with two. pile drivers may be utilized, one on each side of the excavator frame, but where the trench digging is relatively slow and one pile driver candrive the shoring boards into place with sufficient-speed to keep up with the trench the work i work, a single pile driver maybeu'tilized .on both sides of the excavator frame by moving it'around the curve 22 at one end of the excavator frame. I v v Of course I do not wish to be limited to the exact details of construction as herein shown as thesemay be varied within the 1 ley consisting of two side plates having slots therein at the lower edges thereof,the side the appended claim without deedges of said slots converging inwardly or 7 toward their upper ends, rods for securing the side plates in position and holding them.
